609.02(c)    Processing Requests to Change the Correspondence Address Before Registration

Once the correspondence address is established for a particular application, the USPTO will generally not change it unless there is a properly signed written request to do so, submitted via the TEAS Change Address or Representation form. See TMEP §609.02(b) for information about the requirements for a request to change the correspondence address, and §609.02(a) for discussion of situations in which a request to change the correspondence address is presumed.
